This toolkit helps teachers to demonstrate and students to understand a diverse mineral processing method, the separation based on density, through an interesting application, using only a simple physical property of materials. With the help of the experiment, it will be easy to distinguish between a high and low density material, even if the actual densities are unknown.
The target age group is 10 years and older students, as no chemicals are needed, and the experiments can be done in a few very easy steps:
